How it breaks down

CCCXLIV = 100 + 100 + 100 + 40 + 4 = 344
Group	Value	Subtraction	Running total
C	100	—	100
C	100	—	200
C	100	—	300
XL	40	L − X	340
IV	4	V − I	344

Why the smaller symbol comes first

CCCXLIV uses subtractive notation in 2 places: XL means L minus X, or 40; IV means V minus I, or 4. A smaller symbol placed before a larger one is subtracted from it rather than added, which is why IX is nine and not eleven.

Only six such pairs are valid — IV, IX, XL, XC, CD and CM. That restriction is what makes the notation unambiguous: IIII and IC both look like they should work, but neither is standard, and only one spelling of any number is correct.
